40th Mersenne Prime Discovered: "ORLANDO, Florida - December 2, 2003 -- Michael Shafer, a 26 year-old volunteer in the Mersenne.org research project called the Great Internet Mersenne Prime Search (GIMPS), has discovered the largest known prime number. Shafer used a Michigan State University lab PC and free software by George Woltman and Scott Kurowski as part of an international grid of 211,000 networked computers in virtually every time zone of the world."

Something along the lines of understanding mountainclimbers and their desire to scale Everest and every other big rock is needed to appreciate the significance of this particular discovery.
